The climate of New Caledonia

New Caledonia, a French territory located in the southwest Pacific Ocean, is distinguished by its tropical geography. The primary landmass is an island surrounded by a barrier reef and is home to a variety of terrains, including coastal plains, mountains, and highlands.
